SO-8 Package (LTC1693-1, LTC1693-2)
IN1, IN2 (Pins 1, 3): Driver Inputs. The inputs have V
independent thresholds with 1.2V typical hysteresis to
improve noise immunity.
GND1, GND2 (Pins 2, 4): Driver Grounds. Connect to a
low impedance ground. The V
connect directly to this pin. The source of the external
MOSFET should also connect directly to the ground pin.
This minimizes the AC current path and improves signal
integrity. The ground pins should not be tied together if
isolation is required between the two drivers of the
LTC1693-1 and the LTC1693-2.
OUT 1, OUT2 (Pins 5, 7): Driver Outputs. The LTC1693-
1’s outputs are in phase with their respective inputs (IN1,
IN2). The LTC1693-2’s topside driver output (OUT1) is in
phase with its input (IN1) and the bottom side driver’s
output (OUT2) is opposite in phase with respect to its input
pin (IN2).
